In >15 years what I have seen is that OSS comes with a huge cost of attention - that you'd be better off focusing on your business need.
Running most of these OSS even at a medium employee count scale is a full-team-commit-nightmare. It essentially means your it department now needs a specialist who will be able to handle your org quirks, remember the tweaks and keep baby sitting it. Not to mention many OSS teams (I don't know about the above listed) are ever so sneakily introducing enterprise clauses about usage in their EULA.
I don't want to name names, but even with paid software we are seeing this problem everywhere in trying to host: But at least here, we got the actual developers and experts on a call who can walk us through why x employees are fine and x+1 nukes their system.
