Depends on the mobile MUA.  On Android the default mail client is
lousy.  But the K-9 MUA is available for free and provides offline IMAP
and the choice to only retrieve the most recent X number of messages
[although I don't see much point in not having everything available on
the phone - they are sorted after all]

No, of course not.

1:1

May I ask why?  Messages are (a) sorted and (b) highlighted if they are
read or not.

But from all these questions it is apparent that POP is what is
actually making in complicated.  With IMAP it is simple: here is your
mailbox.

To me it sounds like what you really need is server-side filtering.
