You're already off to a good start, but if you want to have full control over those funds, then you might want to consider using a self-hosted processor ^{[e.g. BTCPay Server]} as opposed to a custodial one ^{[e.g. Coinbase]}.
^{Take note: Most of the self-hosted processors are a bit more complicated and that includes the conversion part as well; In other words, just ignore my suggestion if you're after an automated process.}
