Exactly. Buy T, X or P series. For non-demanding users L series might be OK, but I prefer to buy second-hand / refurbished T series instead. Avoid E series, or at least don't expect any "ThinkPad-ness" from it.
TBH, if anyone else brought a remotely competent eraser pointer to market, I'd probably consider them. Even the hyperconfigurable Framework doesn't offer one.
Sometimes you can find a random business-line HP or Dell with one, but the Dell one I tried (some 7th generation Core i5 I rode for five years at work) was so terrible, especially on scrolling, that I just plugged in an external mouse, and it's a feature that appears on random models intermittently when it does appear, so it might not meet any of my other (admittedly limited) requirements.
