Philosophy Compass - good, accessible opinionated overviews of the latest work on particular topics, often with annotated reading lists for more research (full disclosure: I have cowritten one such overview)
Stanford Encyclopedia of Philosophy - excellent overviews of the literature on particular topics. Often longer and more involved than Philosophy Compass articles. Make sure to check how recently a given article was written/majorly revised if you need to ensure they are completely up to date
PhilPapers - a useful database for finding philosophy papers and books, which you can search or browse by topic and sub-topic, easily see other works by the same author, papers related to one you are looking at (e.g. with similar keywords, or papers which are cited by/have cited this paper) etc. Often also has links to archived free versions of papers even when the official version is behind a paywall
GoogleScholar - a database of academic papers generally, not just in Philosophy. Also good for searching for papers on particular topics, though it doesn't organise them into categories in the same way as philpapers. Entries include information about related papers, and includes metrics such as impact factor of the journal and how many citations the author's works in general have. Note that I recommend (1) avoiding the AI-based 'ScholarLabs', and (2) treating citation-based metrics as only a very rough way of assessing the quality of an article/journal/author's work
Bonus: see here for a useful list of tips for using google search much more effectively, from a librarian. Note especially the subtext: going to physical libraries, browsing the shelves, and talking to librarians, can be extremely helpful for finding useful resources. E.g. if there is a book you know will be helpful, then even if you could just download it, it will be useful to see what is next to it on the library shelves! You may also find that reading a physical book helps you avoid distractions associated with being on your computer and to process and retain information more deeply, as several studies have suggested this...
