Hey everyone can you guys tell me the best settings i should set on Electrum i wanna keep it simple

Also what's the best setting to use when sending Bitcoin
static vs eta vs mempool should i keep the slider in the middle?
I also want to keep this simple

Question moving the slider all the way up does it mean higher fee but faster confirmation and delivery?

okay so i needed to cash out some funds from a website and i chose the option to cash out by bitcoin
i tried using the bitcoin address from my ELECTRUM wallet but that didnt work the website i was trying to cash out from said invalid crypto address so i tried a few more

the only one that did work was my bitcoin wallet address from cashapp

is there a reason why only that one did work?
