What don't you like about Feedly? Are you looking for more or less a direct replacement or are there some problems you have or features that you would like in the new tool?
There are hundreds of options out there, but it is hard to recommend anything without knowing what you are looking for.
It feels like they are trying to force more and more their AI features. I would also like to filter based on keywords or regex.

Have you checked out Inoreader?
Inoreader worked okay for me, syncs with the client apps I use, and was fairly Feedly-like. But I eventually went to a self-hosted FreshRSS install due to the ads that got inserted into feeds.
If you’re concerned about things like FOSS, you should consider finding a way to self-host, either on hardware you own or using a cloud VPS. Any service that can sync and keep client compatibility updated is going to incur costs, and they’ll extract that value from you somehow - ads, data slurping, whatever. Better to pay for it yourself so you at least have a clear idea what the relationship is.
