The best is to be able to customize the fee. The static option can be helpful if the mempool is not congested and the fee rate is low. But if the mempool is congested and the fee rate is high, the static will become not accurate.
You can type the fee rate manually and fee rate suggestion with any of three options should be your first glance. Before broadcasting a transaction, double check with mempools, it's what I do and suggested in my thread.
If only rely on suggestion, choose Mempool option is best but even if I choose it, I always double check.
These are the fee rate option for static: 1, 2, 5, 10, 30, 50, 70, 100, 150, 200, 300 sat/vbyte.
Assuming the high priority is 123 sat/vbyte. Static option do make makes it accurate.
The higher the fee rate the higher the static fee rate inaccuracy.
They are numbers on the Fee target band when you slide it from left to right but you always can type the number manually like 1.1, 2.2. whatever number.
Your demand is set the fee rate manually by Static option.
I made inaccuracy there because I wrote it based on my memory. I just check it and with three options, you can type fee rate manually, not only for Static option.
