The HDD macs work very well with an SSD swap (hard in a corporate setting,) or just an external SSD (easy in a corporate setting.) But should have maximum RAM (hard to change in a corporate setting.)

I'm not at all fond of the newer more disposable Macs. Still, they should perform pretty well. One of my coworkers installed browser themes that seemed to be crypto mining or something equally ridiculous once. You may want to create a fresh user without any personalization and see if problems go away. I find Mac users and PC users tend never to do a wipe/install and almost everyone tends to port their problems with them by bringing their home directory even to new machines of the same OS.
