As long as you pay a high enough transaction fee your transaction will not become stuck and will not take a long time to confirm.
If your wallet has an option to use Dynamic fees, always use that. Dynamic fees means that the fee will be calculated based upon the current state of the network. Do not use fixed fees or a fixed fee rate.
If your wallet does not support Dynamic fees, I highly suggest that you switch to one that does. Otherwise, you can use
