My problem is opening links from apps. Sometimes I want a link in Slack (or other desktop apps) to open in my personal profile and sometimes I want it to use my work profile. With Brave/Chrome, the link will open in whatever profile window is active. I can't find a way to make this work with Firefox.

Have you tried making a different desktop entry/shortcut for each Firefox profile and then setting a browser picker as your default browser?
