I can answer the inverse of your question. If a site does not require - cookies - javascript - authentication then it is less likely to be tracking you. There are some clever tricks that do not require those three things, but that is getting into hypothetical and less practical territory. If you are using NoScript / uBlock or uMatrix / Self destructing cookies or similar and not logging into any sites, then your odds of being tracked are fewer. If you run a combination of BleachBit, CrapCleaner and BCWipe every time your browser closes, then your odds of being tracked are fewer. If you have an application firewall that prevents applications from chatting with the internet without you explicitly initiating the communication, that also helps. They may contain user-identifiable strings and may share browser functions. As for LastPass, I have always steered clear of sites like that. This may have changed, but for a long time, they required your vault decryption password to sync with their site. Unpopular opinion, I know.
