I've been wondering for a long while now, why do some handguns have the recoil spring on an enclosed rod, and why are some separate?

I have a stupid question

Design differences I would hazzard. IIRC the 1911 as designed didn't have a full length guide rod whereas now some companies include one; such as Smith and Wesson.
With a Glock I would suppose that it is one less object needed to assemble after cleaning, since it's guide rod and spring are one unit.
Hope this helps.

As far as I know it's just a design choice. There are some pros and cons. It's easier to clean the two-part systems but the captive springs don't fly across the room nearly as far as the non captives. There are aftermarket options but I doubt you could convert all pistols to captive or non-captive for specific design reasons.
My Glock 27 has two springs which are captive. It's not something I'd want to take apart every time I break it down. I think my HK has something similar.
My Sig 226 has a separate spring and rod but when new the spring does in fact have a preferred orientation. The tighter fitting end goes on the rod first otherwise the tight end can bind on the rod and short cycle the system. Best thing to do: don't take the spring off the rod if it stays on.

There are two major semi auto pistol types. Strait blowback and short recoil. The PPK type design is a strait blowback and is limited to cartridges equal to or smaller than 9x18.
The 1911 John Browning design is what almost all large caliber modern semi auto handguns are based on. One piece rod, 2 piece, 2 rods, it makes no difference. jp
