One thing I’ve never really looked into before and a topic I’m having a very hard time finding information about:
Are drivers that require smaller enclosures inherently better than ones that require larger enclosures? Vice versa? What is one sacrificing over the other?

No. It is all abut the compromises you are willing to make.
Germain is Hoffmann’s Iron Law:
Box size, bass extension, efficiency. Pick 2.

What does this mean specifically,’drivers that need a small enclosure. ‘ ?
What are you bassing that off of(no pun intended😀)?
Because it’s glued to iron, but tuning can be bad or good and the distribution of size matters (efficient or low?? Are possible for a given size)... higher order functions might help if you accept the iron law is big.

If you want a small enclosure then you either have to give up sensitivity, or bass extention.
How small is small? I usually consider small less than about 7 litres gross volume.

Yes sir. So if just basing size on Vas, it gets tricky in fancy versions if vented. IE huge expanding path TL. but small Vas driver. This is far out on the ridiculous size for many people, but not always, and sometimes interesting or fun to explore if we accept size as whatever it will be and just go for it. Even if 150 liters is the max or something, it’s an aweful Lotta ideas if gathering thoughts from lots of peoples brainstorming. And anyone can scale or downsize as needed?
I used to get a lot of good ideas this way. Granted I had to learn a few big mistakes in lack of space needed.. shrinking isn’t always so good, and it’s a hard lesson I admit

By small enclosures, are you talking about a seemingly large driver in a rather small box?
Loudspeakers enclosures exist of many types & function differently...the two most common are the sealed type, built such as they are sealed & are pressurized by the driver. The other is the ported types, usually a larger size than the sealed types, they use the internal box volume to augment the function of the big driver.
Both the two types require a series of mathematical specifications called the T/S parameters...a mathematic collection of specifications created by two individuals, Thiele & Small, a pair of scientists.
By these collections of specifications, one can create an appropriate enclosure, some work best is sealed enclosures, other work best in ported enclosures.

Scenario:
I had some 15” subwoofers that should have been in 340L ported enclosures. However, I had them in 100L enclosures. Feeding them their rated power, I blew 2 of them.
I replaced them with subwoofers that call for 106L enclosures. They are handling the power just fine now. It made me curious if drivers designed for smaller enclosures are actually superior in some way, so I tried researching reasonings behind why some are designed one way versus another way, but I came up with nothing, so I asked here.

Drivers in small cabinets can give a compressed kind of sound, i prefer using large cabinets or open baffles as they give a free kind of sound.
Creating a bass port can increase power handling capacity, moving drivers around into different sized cabinets should not affect power handling capabilties.
It could be that the manufacturer overhyped the power handling in an effort to boost sales, a very common practise with peak power handling, rms power handling, ( the list goes on and on ) about ways to manuipulate amp and speaker power handling figures.
Perhaps you experienced a peak surge.
If you are driving your speakers so hard that they are blowing you need to get higher power speakers as distortion can increase from amps and drive units when pushed to near their maximum capabilities.
