FWIW, I was in the same situation when we went remote back in 2020. I tried multiple headsets & Settled on using the Apple EarPods that used to come free with iPhones & apple now sells for like $20 or $30.
Here's what led to that. First, I wanted a small headset package. Work gave us some plantronics (or similar) headsets and they worked fine, but they were big and bulky & there really wasn't anywhere to put them that got them out of the way when I wasn't using them. Sure I could pile them on the desk, but I don't want to look at that all day.
I tried aipods, but there are 2 things I don't like about them (I have AirPods & use them extensively for personal use). 1. I don't want to be buying new headphones for work when they wear out. Just a personal preference, and if your work reimburses you, then that may not be an issue. & 2. I only wear headphones when I am on calls & with a Windows PC, I found that sometimes I would still be connected to the AirPods after a call & would have to go into settings & remove them. That could 100% be user error, but it was annoying enough that I didn't want to deal with it. Also, I did some testing & the wired headphones sounded cleaner. (that being said, most headphones, including the AirPods are totally fine for work purposes.)
I tested the EarPods using a 3.5 mm connection, using the apple 3.5mm to USB-C connector. and using a third party adapter from amazon (both USB-C & USB-A versions of it), and also my AirPods & the Plantronics one from work. This wasn't a scientific test & YMMV, but I recorded what I sounded like on webex using each of the connection methods & found that the generic adapter (both USB-C & A) provided the best audio (the plantronics was equally good when used with the plantronics-supplied usb adapter, but not when plugged into the 3.5 mm jack). I've been using that same setup since 2020 with 2 different companies/ brands of laptops/ video conferencing solutions & haven't had any complaints about sound quality on any work call ever.
I'd be happy to share the specific adapter that I use, but it's a generic adapter that looks like most of the other ones & I suspect that they all perform about the same (that being said the apple adapter was noticeably 'flatter' in playback), and I don't want to turn this post into an advertisement for some adapter.
