I'm fine with OpenNode https://www.opennode.com as well.
They are US-based, well regarded, have excellent tools and integrations - and most importantly support Bitcoin via Lightning.
They take 1% for the fiat conversion (i.e. direct USD payouts), which is pretty much the standard for all-inclusive, carefree providers.
But yes, no Monero. As @pablof7z pointed out, there are multiple private swap services for XMR users to get a few $ into BTC once a month.. that shouldn't be too much of a hurdle.
In general, finding a processor does offers both Monero and fiat payouts (USD) is a challenge. The only one I am aware of is https://nowpayments.io and they charge 2.3-1.5% for the USD conversion (on top of the general 0.5% for each transaction).
The reason, since you asked @Vlad, is purely regulatory. The tech is there and trivial.
State and regulators hate private payment (if cash was invented today, it'd be banned immediately) and they have grown accustomed that they can make Visa, MC, Stripe, Paypal & Co essentially perform police tasks without having to involve a judge.
So they apply all kinds regulatory pressure to banks who offer fiat off-ramps, especially for Monero.
Thus, the unfortunate reality it that either processors
- accept privacy coins but do not offer fiat cashouts << like Coinpayments that I mentioned earlier (sad to hear they didnt respond n the general contact email, but they have a dedicated Business inquiries section which may be more suited https://www.coinpayments.net/supwiz-other)
-or-
- do fiat cashouts, but shun privacy coins and stick to Bitcoin (and a few other major ones).
