I don’t use the ratings, but I’ll “heart” songs I like.
I scrobble my playing from navidrome using listenbrainz and tell my two clients Tempus and Feishin to use the scrobbled data to build dynamic playlists. If I start with a particular song or album, the mix following that is usually kept in the same mood, only strays into weird stuff once in a while, but no more that YouTube Music used to.

In tempus, the setting is called “continuous play”. In feishin, it’s called “auto-dj”. Both settings are turned on by default, so you shouldn’t have to do anything.
Scrobbling helps because every played track goes into played history, and play counts help dynamic song selection more and more over time.
