There's one (related) difference - an LP can hold approx. 45 minutes of music, a CD can hold 80-ish (The original spec called for 74, but I think the most I've seen on a single disc is 82-ish minutes).

Unless an artist is very disciplined, that means what would be a decent album at 40 minutes worth of music in LP days would be half an album today.

Again, this is a shortcoming in people, not in the medium itself - after all, a stellar 40-minute album can be released on CD, too.

I have heard expressed many times, though, the expectation that a CD should be 'full' in order to be a proper product - or, for that matter, the artist can be less severe in the cutting room, seeing as 'Oh, we've got room for that one, too ...'

I'd much rather have a condensed album which is mostly great than the same songs mixed with as many tunes which ought have been left in the archives pending a 'Collector's edition', 'Complete outtakes' or similar.

Then again (again!), at least a CD lets you skip the filler and listen only to the good stuff - at the risk of losing some of the recording artist's vision. Which, again, is a matter of (lacking) self-discipline. The LP raises the bar for skipping songs, hence forcing us weak souls (I count myself among them!) to listen to the full work, as the artist intended.

Or, at least as the artist intended before 'new release' meant uploading a new song to streaming services, making the album - as a somewhat cohesive collection of songs - a niche product.

Apropos nothing, the latest album I bought is a CD which arrived in the mail today, and it clocks in at 55 minutes and 20 seconds. Picked up a handful of LPs last week, though.
