Recumbent bikes can promote over flexion of the neck, sometimes. Your neck isn’t neutral, it’s bending forward slightly, like tech neck. That’s not to say a recumbent isn’t ergonomic on the whole, but there are trade offs.

Yes, absolutely. Although the neck issue is mostly solved by a 3/4 recumbent (which is what I used), where you are not completely flat.

A potentially worse problem is that recumbents allow enormous force to be applied through the legs (because you can push against the lower back, as in rowing). This is one of their superpowers but you need to be aware of it to avoid knee issues.
