I have a pair of SPD SL cleats and pedals. I want to switch pedals to the small SPD clipless for commuting. Is there a pedal that accepts both SL and regular SPD?

I'm confused, do you mean shoes?
SIDI road shoes can take both 3 bolt
and 2 bolt cleats.

Nope! Not that I've ever seen anyway. Sorry!

Schwinn made a pedal that was SPD on one side, LOOK on the other and had a snap-in toe clip. Made for spin bikes but would give a lot of options if used on a utility bike.

You mean you want SPD for commuting and SPD-SL for other types of riding? I totally understand but I don't think there's a product that will let you do that.

I prefer the SPDs for commuting too but my feet get numb on long, hard rides and the larger size of the SPD-SL helps a lot. The solution is two bikes or to switch pedals. I commute on my SPD-SLs during the portion of the year that I'm doing a lot of recreational riding. I use Lake CX-125s which are pretty walkable for a road shoe but they're no longer made.

Holy ****.

So I was wrong. Learn something new every day...
