I have to be careful with planks because I have either an arthritic hip or a bad groin or lower stomach muscle injury.

I quite “enjoy” basic planks and side planks because of the challenge of prolonging them.

When I was in my late 20’s I could do a 1000 sit ups without stopping so the pain from planks is something I seem to be able to bare.
