Old macbook air 2012, bootcamp with internal third party ssd/adapter vs. vmware vs. win2usb external ssd, no good options?

Catalina 10.15.6

Got an old macbook air 2012" that I like and can't afford a new one anyway, I want to run windows just for very few programs, I got this adapter/ssd for my mac in general.

and this 1tb ssd

Bootcamp would be ideal option, but I didn't know about all problems with running bootcamp/installing windows with third party internal ssds and don't want to run into that and troubleshooting it when there's partition problems.

OWC drives with their special firmware and software for bootcamp and all that might have worked but it's not worth it they're 3x more expensive than third party drives.

Win2usb probably won't work well on usb3 speed, booting a MacOS clone from usb3 is painfully slow.

Similarly parallels or other vmware would probably not work well because of the notebook only has 4gb ram, and cpu can get a bit hot running multiple programs in MacOs, but performance is generally not slugglish.

So, for this laptop, just no Windows or are one of these options worth a look at?
