It is literally that simple. That thinking has already been done by the FDA when they approved the vaccine and when they approved the boosters. The FDA is very conservative when it comes to approving new drugs and therapies (perhaps too conservative, but that's another comment entirely). If you're not going to trust the FDA, we don't have anything to say to each other, really, because that's what the FDA is for. They have a great track record on these things, with very, very few drug recalls happening due to unforeseen side effects. As far as government agencies go, when it comes to drug approval, the FDA is probably the most trustworthy and least politicized government agency we've got. They've examined the data on myocarditis and recently approved boosters for people over 16. They haven't yet approved it for 14 year olds, so, yes, that is an open question. But, it's one which they're working to answer, and which it's essentially part of their mandate to answer.
