Russia is pretty bad.
There are various sites and rankings of best and worst countries, here's one from 2023:

Roughly, getting into an EU country or Canada would be the best. It's very difficult to immigrate to these countries, though - especially the ones best for trans rights tend to also have very strict immigration requirements and laws.
To be honest, Russia is so unsafe I would just prioritize getting into any Western country. Trans rights are undergoing a lot of change, places like the US which traditionally were very good from trans rights and healthcare perspectives have shifted to the right and become anti-trans. Canada is seeing the rise of a right-wing populist movement that has connections to the anti-trans movement. Anywhere you go is not guaranteed to be safe, so it's important to think practically about what matters most to you.
It's good to be in a safe place with strong rights (living in California for example would be a great option), but you have to consider access to care, what care you need, what it will cost, etc.
And prioritizing those needs might also be important - Russia simply isn't safe, so getting out is the top priority, probably.
