Sorry I think I didn't explain very clearly, gas limit is NOT refunded, but any extra msg.value will be and a too low msg.value will cause the tx to revert, which is why msg.value should always err on being set very high.
The gas limit does affect the fee that is deducted from the user, I think we can mention somewhere that they can use eth_estimateGas to get a more accurate real-time estimate for what to set it

The gas limit is not refunded. The gasLimit * baseFee is the fee that is charged, and if the msg.value is higher than this fee, the remainder of the msg.value is refunded. Conversely, if the msg.value is lower than this fee, the tx will revert
