Not that a lot of these are "bad" ideas, but it seems like giving 1 person or family $600 worth of help makes a way bigger impact than giving 600 people or families $6 of help. Direct giving is going to be the biggest bang for your buck.
At most, I might say pick 5 or 6 targets of good people who are likely to be struggling (ie, ahem, sound guys *cough*) and who aren't likely to have other avenues for help. Those are the people who are really getting hammered this past year. Everyone and their mom is donating to "food banks" and the like, so those are covered anyway, but do you think the people you are trying to help would rather have $100 bucks worth of beans and wonder bread, or $100 in cash to spend on whatever it is they need most (and almost certainly still have access to the $100 of beans and wonder bread).
So yeah, target that favorite sound guy in town (who probably hasn't done any sound in 9 or 10 months, also, remember that at least musicians can give lessons, sell music, merch, etc... and have "followings", sound guys are basically invisible, unless a musician or group of musicians advocate for them essentially) or musician, or venue worker (who might not have an easy way to switch to doing something else right now), etc... Pick somewhere between 1 and a handful and maximize your impact in a concentrated group, rather than diluting your impact among as many people as possible.
Now, if you want to get together with a group of likeminded friends in a similar position, so you can help more people, that's great. But I think the people in the shadows who aren't really able to get the help that's already out there are the best place to put your money.
