Fix the constraint first
A home-office problem may be heat, glare, noise, chair fit, monitor height or Wi-Fi. Do not buy new gear until you know which constraint is real.
Check repeat daily friction
The right purchase solves the recurring problem, not the most visible one. Track what annoys you for two workdays before buying.
Check space and cables
Desk depth, sockets, cable paths and router placement can defeat otherwise good equipment.
