It's the same in Wasabi, you right click an unconfirmed transaction in your history and select "Speed Up Transaction".
OK, but can a Wasabi wallet user decide what kind of speed up they want to do? Can they choose between RBF and CPFP themselves or does the software do it for them? Your docs section makes it sound like the Wasabi wallet makes the decision of what to do. Obviously, it's better to do an RBF, but it's good to know for clarity. With Electrum, I can do a CPFP if I want and control the change address or destination address. If it is an outgoing payment, RBF is automatically used for transaction speedup (since it is more blockspace efficient than CPFP). If it is an incoming payment, CPFP is used (since it is the only possible option for speedup). You could CPFP the original transaction instead of using RBF by spending the unconfirmed parent through the normal send workflow (not recommended, since you should coinjoin it first), but you are correct that there's not a CPFP option listed alongside RBF when RBF is available.
