I don't have the reMarkable 2, but I preordered v1 and have been using it pretty regularly since then. I've really enjoyed it and greatly prefer it for my primary use case of reading and reviewing academic papers. I find it far superior to an iPad in this respect. Mostly because of the display.
The specific points of feedback you have are common with the v1 device. With the exception of pressure sensitivity. The pen for the v1 device was pressure sensitive. Has that been removed? Of the other points, the only one that I've found really bothers me is being unable to change the default writing implement.
If it has pressure sensitivity, it seems to be a random number generator. It does some stroke thickness tweaks depending on speed and maybe the angle the pen touches the screen with, but my experiments of drawing a straight line at constant speed with variable pressure have yielded a line of constant thickness every time.
