"Ad blockers" nowadays do much more. From the horse’s mouth, which describes itself as a “wide-spectrum content blocker” [1]:

“uBlock Origin (uBO) is a CPU and memory-efficient wide-spectrum content blocker for Chromium and Firefox. It blocks ads, trackers, coin miners, popups, annoying anti-blockers, malware sites, etc., by default using EasyList, EasyPrivacy, Peter Lowe's Blocklist, Online Malicious URL Blocklist, and uBO filter lists. There are many other lists available to block even more [...]

Ads, "unintrusive" or not, are just the visible portion of the privacy-invading means entering your browser when you visit most sites. uBO's primary goal is to help users neutralize these privacy-invading methods in a way that welcomes those users who do not wish to use more technical means.”

Disable JS and you've eliminated the vast majority of fingerprinting (besides "blocks JS")

Depends on what lists you use. If you use uBlock Origin, and enable most of the lists, it'll target both.
