for as ubiquitous as electronics, i have yet to find a great single source of information on them.
i personally have a copy of Jaeger's Microelectronic Circuit Design that i bought for like $5 that i find surprisingly enlightening

Horowitz's The Art of Electronics is a commonly cited authorative book, although i've never gotten past the first couple chapters

truth be told, once you have basics under your belt, the application notes on datasheets are probably the best source of hard information on anything. buying parts and experimenting with them (or running simulations e.g.
https://www.falstad.com/circuit/ or SPICE) is irreplaceable to understanding
i think learning electronics is difficult because it's a huge pile of approximations. i find it easier to start with maxwell's equations and then apply the approximations to derive circuit theory and other models. this is because maxwell's equations are what unify everything, so rather than memorizing a constellation of seemingly unrelated models with fuzzy domains of application, you can see how those models arise by making particular assumptions and approximations that fit the given thing under study. while it is a circuitous path, learning E&M first is what i'd suggest to somebody that really wants to know their shit, then start on electronics. the best resource for that is Griffith's Introduction to Electromagnetism.

this will teach you very little about practical electronics, but it will well prepare you well for learning more about electronics in a structured way.
