Well, most of popular in the world VPN services are already blocked. Even such simple things like Cloudflare's warp doesn't work, although it still possible to use it if you generate wireguard config and change endpoint, but there's a possibility that the wg protocol will be blocked in the future. The best way to bypass censorship in Russia right now is to use Chinese solutions for gfw circumvention such as shadowsocks/vmess/vless/trojan/etc. Or one can use self-hosted VPN servers, but it's very hard to find a way for paying for cloud services that are located outside of Russia.
