Suggestion: video on converting voltages, current, etc.

I'm still very new to electronics, and when I start integrating various simple circuits built in isolation I struggle with getting the right input voltage, current, etc. for each sub-circuit ("stage"?) given a single power supply. During development, a multiple-output power supply is fine, but how do I build the circuitry to power everything from a single power supply? Maybe I missed it, but I don't think the electronics tutorials playlist has anything like this.

A video on the various ways of getting the right voltage and current as the input to a circuit would be really useful. There's plenty of information on voltage dividers, voltage regulators, and switched-mode power supplies, but what are some other options? How do I pick one when I have a set of constraints, like the first circuit connected in series outputting a dangerously-high voltage/current to the next circuit. I'm particularly interested in those that can be used between circuits rather than connected as a master supply. Some topics might include buck/boost converters, inverters, buffer amplifiers, cascade/cascode, etc. - not really sure, because I don't know!

Also, a basic explanation of how to model circuits using Thevenin and Norton's equivalence theorems with common gotchas (like using components that invalidate the theorem) would be useful - things like how to choose values for current-limiting resistors, how/when to use constant current/voltage sources, etc.

I'm a slow learner and novice, I would love that! Also, tutorials about KVL and KVC, also Gauss for dummies.

This teacher has interesting videos, too...
