There is a lot of cool router configurations examples around but they almost all involve configs with IPTABLES but openwrt uses NFT. Is there a guide in an understandable language around or a tool that does it automatically? There is a package "iptables-nft" that seems to offers tools but the description is incredibly vague.
Do you have any examples of these 'cool' router configurations?

-m mark/-J MARK is problematic that you can have one from iptables via xt bridge other native nftables and they do not exchange attributes.
The rest of rules are pretty generic, you can even make them into fw4 (and fw3) rules and ignore different backend rulesets.
You just need to check if xt bridge rules are present in nftables ruleset and add more nftables kmods as in dictionary at:
