For Chrome/Chromium browser
Browser/device fingerprinting reduction can be done using
DJ NoScript

DJ NoScript don't support Font Fingerprinting so need to use
Font Fingerprint Defender for spoofing
Defending against Font fingerprinting by reporting a fake value.

Note: - DJ NoScript don't handle hardware fingerprinting like spoofing screen resolution/CPU cores/GPU(but block WebGL fingerprint)/RAM/mouse movement etc nor OS, client hints, navigator spoofing etc
Other extensions include
Classic Cache Killer - To remove ETags
Ping Blocker - To block beacon, ping and CSP report
Chrome History Cleaner - Cleans history within 1 min (minimum setting)
IDN Safe - IDN Safe is a browser extension which blocks internationalized domain names to prevent you from visiting probable fake sites.
Keyboard Privacy - Prevents behavioral profiling by randomizing the rate at which characters reach the DOM.
Trace - Works similarly like DJ NoScript but with additional spoofing of hardware like CPU cores/GPU/RAM/screen resolution. To avoid duplicate with DJ NoScript disable those same protections either in DJ NoScript or in Trace. I'll advise spoofing hardware using Trace and leaves the rest to DJ NoScript
However, beware of using excessive extensions in Chrome/Chromium browser
