I have tried En Croissant and its personally its a nice GUI and easy to use. It allows you to download stockfish and others right from their GUI.
I don't play Chess much any more but others have taken up the Chess DB mantle (with slightly different criteria).
I do find it ironic that a project I did in a couple of days for myself and chucked online in case it was useful is still kicking around though.
If you like En Croissant there is a nice fork called Pawn Appetit that does all the same things and adds some other QoL bits and bobs.
