Depends on what class of monitor you want to run it with. A KVM that can handle 4K 144hz VRR is... not cheap, if available at all.

He bought a $900 monitor that has a KVM built in

No, the worst part of a KVM switch is the video signal switching. You want as few switches in the video signal path as possible and the higher bandwidth you need them to be the more expensive they're going to be. You're already paying for the one in your monitor, so taking advantage of that is the right solution.

IME even high-end KVM switches experience occasional signal interruption or, more often, failure to synchronize at all on output switch.

Do what OP did.

Depends on your threshold for "fiddling". The author's is quite inclusive.
