Yes absolutely.

If I have to I trust the company's CA in a special browser profile that I only use for working with their internal tools.

For just a few tools it's often simpler to just trust those specific certificates, though

All browsers can tell you what certificate signed the one in use. Unfortunately a recent chrome UI change made this a pain to get to.in chrome, into the other browsers just clicking on the lock in the address bar, it soon becomes obvious if the company is mitm all SSL connections.
