The values are… mostly the same on all the territory but somewhere is more strict especially on gender roles and sex relationship fact:

• Traditional family (marriage between man and woman, have kids more than one), gay marriages are strongly “NO GO” and “NO” to adoption by one sex parenting (in Caucasus and Chechnya those rules are even more strict, too strict to risk); Recently, in 5th of 2022  “Gay propaganda”, “Sex change” was completely banned by criminal law. Jail would be the home for 3rd, 4th, 5th …and many more genders that are written in the “drag queen bible”.
• Not patriarchate but still gender roles are assumed for a man to be a bread winner and a woman as a family “carrier” or “holder” you name it (who take care of the house, raise own kids and keeping the family’s bond);
• Not forcing anybody to believe and engage with the church/religious practices (christians, muslims, jewish freely live in one city, area, street); Yes, sometimes it’s not too ideal but to this day they managed to still coexist with each other. 
• “Once word given cannot be taken back” — a man of a word, and therefore Russians are not so light-minded when promising smth, this is one of the features why China and Middle East, who heavily rely on this factor when making alliances, are now good friends with Russia — in many cases, keep on promises and give a meaning to any word, thats the motto.

Most known Russian ethnic groups in Russia are… (where do they live):

• Armeni or Armenians(Central, South. Christianity as a religion but not so about religion. One of the largest ethnic minorities and the largest diaspora. More on traditional views and family norms. “Kochari” is the traditional dance that was listed in UNESCO cultural heritage. Bravo Armeni !)
• Azerbaijani (Central, South. Profess Shia Islam but they more for a freedom of religion and so, some of them could be christians…not that I know tho. Food, dancing “Turaji” “Uzundere” “Terekeme” “Mirzai” ” Gaitagi” “Askerani”, and singing — essential things in their tradition)
• Tatars (mostly live in the Central and Volga region. They profess islam and have their own region called as Republic of Tatarstan and Kazan is the capital. Family traditions are “must” and always prefer to marry same nationality…However,  some Tatar women prefer not to marry Tatar men, for a reason — Tatar men are demanding (for house carrying) and very jealous or how they say “too protective”, well, you call it )
• Caucasus (mostly live in the South.They profess islam as well as their neighbouring nationalities, Chechens. Carefully hailing their national and family traditions. Welcoming hosts but respect those who respect their religion and moral values, which include the proper wear (longer skirts with shoulder cover for women, and men should not walk around with naked torso) You’ve been warned!)
• Chechens (mostly live in the South. Have their own Republic situated in the North Caucasus between Caspian sea and Black sea. Brave warriors when it comes to military service and diligently follow their traditions, which are religion respect (islam as their religion), respect for the elders, show politeness, modesty, respect for women, hospitality. As I mentioned above for another nation, Chechens are welcoming hosts, but respect those who respect their religion and moral values, which include the proper clothes to wear (longer skirts with shoulder cover for women, and men should not walk around with naked torso))
• Cossacks ( mostly live in the South of Russia, known for their privileged military class status during the war, skilful horse riding and use of bladed weapons, and brave temper, of course) 
• Kazakhs (mostly live in Siberia, Ural, Far East. Kazakhstan is the country that boarder Russia in the South Siberia. One of the largest diaspora here.) 
• Bashkirs (mostly in Siberia and Ural. Its Kipchak-Bulgar Turkic ethnic group indigenous to Russia. One known thing about Bashkirs — they are the honey makers! Bee-keepers, agriculture, cattle-rearing . Wild-hive beekeeping is another attested tradition there)
• Buryats (Siberia, Far East. And this ethnicity is known for religious practices like shamanism (Tengrism, with a focus on worship of nature), ancestor worship, and Buddhism. If to trace back in time they were part of Mongolian Empire so cultural and linguistic traits are shared…and mixed with Tibetan. Unfortunately, cant be certain with their marriage culture: when they marry, how they marry, their gender roles,…) 
• Jews (Central, North West, Volga, South. Follow Judaism as a religion and prefer same religion marriages. They do like to participate in major events, earning academic achievements, very savvy in economics, politics and law enforcement) 
• Yakuts (Far East. Horse racing, wrestling, and all-night line dancing to improvised chants. The Diamond land, not figuratively. 90% of diamonds and 40% of the gold are extracted in Yakutia So, dancing with the diamonds and deers, “igloo”* people — the image of Yakuts who live in such a freezing to the bones territory in winter and forest burning area in the summer)

*Igloo –winter home for hunting-ground dwelling of Canadian and Greenland Inuit (Eskimos). The term igloo, or iglu, from Eskimo igdlu (“house”).

They are Russians as they were born and now fully citizens of Russia, just to make it more clear for you, as there, below, i mention ethnicities that belong to other countries, like most Armenians do live in Armenia, but there is a big number of Armenians that were born and one-country residents (in Russia), and so they are Russians (or as they also call themselves — Russian-Armenian)
