It’s not been a problem for me. The registrars I use are pretty vocal about expiring payment credentials, and if I were really worried they allow stacking multiple methods to fall back on, some of which have their own fallbacks (like PayPal). In theory paying for longer periods in one go could help, but ironically that might make it worse since you’re more likely to forget about a renewal happening 5 or 10 years from now than you are one that recurs every year.

You can always register the domain for 10 years, and then just keep renewing it every year so you always maintain 9 to 10 years of future paid registration.

Like you, this hasn’t been a problem for me.
