I notice that among my own collection of academic PDF papers, some are 3:2 though most seem to be 4:3.
My question is: Does the aspect ratio of the tablet screen matter? And do PDF files adjust themselves in any way to fit a given screen's aspect ratio?

You might find the screen portraite width to be as important to you.
e.g. A4 and US-letter sized documents are 210 cm and 216 cm wide respectively, and the text column width (without empty margins) is usually about 17-18 cm wide.
Samsung Galaxy Book 12; 2160 x 1440 @ 216 ppi = 16.9 cm width in portraite
iPad Pro 12.9; 2732 x 2048 @ 265 ppi = 19.6 cm
So, on iPad we could read some of them in portraite mode even with intact margins thereon or get a considerable magnification by reading without margins (zoomed in without margins or with margins cropped by 50-60 %).
Similar is the case with 10"/11" readers in the landscape mode, where we might find those with wider screens in landscape (i.e. with longer screen in portraite), better suited for reading wider pdfs and comics.
