There are very good USB mics like the Blue Yeti for example. Plug and play with just one cable. You don't have to have a studio recording setup to get your voice to come through nicely.
The Blue Yeti is an okay mic, but is a little pricey for what you get and also buys you into some other stuff you may not want to spend the money on, like a bit of a heavier-weight arm, etc. to be close to one's mouth. It's also a little sensitive for spoken word and while it can sound great in a treated room it's not great for conferences or untrained users due to its habit of picking up a lot of ambient noise through untrained positioning or habits (drumming on a desk, that sort of thing).
Most folks I know recommend the Samson Q2U or the Audio Technica ATR2100 instead as easy mics to deal with for untrained users; shameless plug, but I wrote an article for Mux about this not long ago which explains in some depth why one mic may be preferable to another for untrained users: https://mux.com/blog/zoom-like-you-mean-it-1/
I wouldn't get a Blue Yeti for voice calls. Besides being pricey, it's a condenser mic and a lot more sensitive and prone to picking up other sounds you probably don't want.
Something like the Audio-Technica AT2005 also supports USB plug and play, is half to two-thirds the price, and is a dynamic mic so will reject a lot more of the undesirable sound before it even gets into the computer.
It's easier to not capture undesirable sounds than it is to try and clean it all up after.
