Commit Charge in Win10, hovers around 15GB or more. Should I get more than 16GB of DDR4?

Ryzen CPU rig. Doing some mining in the background, that seems to take up RAM.

Firefox Nightly, and Skype, take up a bunch too. (Lots 'O tabs.)

Was wondering, how much RAM should I throw in this box to be comfortable?

Kicking myself for not buying a pair of 32GB DDR4-2133 kits when I saw them last year or so ago for $110.

16GB is plenty for most. Since RAM prices were so high at the time, I initially tried to get by with 8GB, but with doing multiple things at once (including F@H), it was a little tight. I bit the bullet, and picked up another 8GB kit to make it 16GB, and I haven't had any complaints since.

You haven't disabled your page file by any chance have you? If not, between it and the amount of RAM you have, you shouldn't really be running out of available RAM. Windows 10 might commit/stand by some RAM, but you really shouldn't be using it all doing some mining and web browsing (even with a lot of tabs open).

Total, limit or peak?

Simple answer: how many page faults per second are you getting in resource monitor? If you're not getting many, you don't need more RAM. The rest is housekeeping, and modern OSes will "use" all the RAM you throw at them, regardless.
