I never even thought about this before, but what kind of hardware is a root level DNS server like 1.1.1.1 or quad 8 run on? Are they all roughly the same, or do they take different approaches to the load?

Bit of a nitpick, but these providers are not running root servers. They’re just recursive caching servers, probably running unbound.
If you want to find out root servers - dig for . - that’s a dot. A full stop. That’s the root. Those can then answer where to find your .coms, .nets, etc. Those, in turn, handle the domain you rent; so on and so forth.
