My current thoughts lean towards a fully functional open source product with a HashiCorp style BSL and commercial licensing for teams above a size threshold.
if you want to promise open source software simply to attract the mindshare and users who habitually ignore anything that isn't open source, trying to capture financial value may well be infeasible unless some rare confluence of stars lines up for you. the key is in the word "capture" - capturing the value implies making sure it goes to you rather than to someone else, and that means imposing restrictions that will simply piss those same users off.
Many corporations wouldn't buy licenses and those that would pay for support wanted support for hardware that was 2 or 3 generations old.
Gentle reminder: please encourage your corporation to pay for open source support whenever possible.
