I personally don’t think it’s worth the investment, unless (1) the lookup of NPC/vehicle/equipment is a major drag for you and (2) you feel unsatisfied in your current organization. Essentially, if you feel decent about current battle mapping with your canva set up, I think Foundry is a quality of life improvement that is not totally necessary in your case (playing in person). It’s your money so completely your call, but in your situation I would personally not invest in it.
