I’m also nervous about using an OS I’m not familiar with for business purposes right away
Absolutely STOP. Do not go with Linux, go with what you are comfortable with. If this is business, you do not have time to be uncomfortable and the learning curve to ramp up to ANY new OS and be productive is something that's just a non-negotiable kind of thing.
If you've never used Linux, play with Linux first on personal time. For business time, use what you know works first and foremost.
All OSes are tools. You do not just learn a tool when your job is waiting for a bed frame to be made or whatever.
TL;DR
If you are not comfortable with Linux, do NOT use it for business.
