I got a TecWare Phantom 104 for my first, it’s been good so far (about 3 years of use). The “shroud” cover piece helps with noise and light leakage. I have the brown keys, they’re pretty nice. I’ve had to replace a couple of the most used ones, but it came with some extras.
The keyboard comes with a key cap puller tool, but I recommend getting a key puller tool (to remove the keys themselves, not just the caps). They’re cheap and will make changing keys a much better experience.
HR does exist to protect the company, but sometimes that aligns with your needs. In this case, HR is likely more interested in avoiding a sexual harassment case (which would cost the company), so they’re probably going to hear you out.
