There are a couple options with the pressure of the Wacom Tablet, it really depends on what works for you. What I've found is it needs a bit more sensitivity than photoshop.
Pressure sensitivity (pen to pad) can be changed by going to "Stroke" which is next to "Brush", you'll see the "properties" tab click that and you'll be able to change the pressure of the pen to pad and how it looks on the page.
You can also go to the system preferences and select Wacom tablet, there'll be an Affinity icon in the top "Applications" window, select this and then select "pen", here you can change the Tip feel which is the feel that would best suite you. I find having it in the middle is best.
I hope I've been a help.
Have a great week.
