Often overlooked middle-ground that vastly simplifies your revocation logic: Just have a single field "not-issued-before" timestamp assigned to each user account. Instead of revoking a single token, you have a "log out from all devices" logic - i.e. you revoke all tokens at once based on their "iat" claim (issued at). No need for revocation lists alltogether, you just make sure any tokens "iat" is never before the "not-issued-before" associated with the user. Sure, this is not as perfect UX as being able to revoke individual tokens, but token revocation in generall is something only a fraction of your uses is ever going to need.
