I really like Japanese with Shun (on Spotify, I don't know about other platforms?) and also Comprehensible Japanese (here on youtube) which has lots of free content, also a dedicated site with extra material for Patreon supporters.
Shun's good cause he speaks slow enough without being annoying, and enunciates quite well.
Basically the same for Comprehensible Japanese! Though these are extra nice since there's an extra modality (namely video) which she uses so that you can continue listening with context.
