I think the smart thing to do is to trace each circuit using the pjotofact, test for capacitance and resistance, and move down the circuit. Is that a best practice?

That would be a way to do it. You also would become more acquainted with the circuits. Sort of an aid in learning.
However, capacitors as old as in this TV have a very high probability of being bad, not every one but most. Some bad parts cause big problems, some just cause lack of best performance. Some might be OK for the moment but soon fail. You can't tell unless you completely test each one, that takes a lot of time and effort. You really need to unsolder at least one lead to test a capacitor. You should test for capacitance and leakage at near rated voltage. The other approach is to replace all the electrolytic and "paper" internal construction (some types of paper caps have plastic cases) capacitors. Resistors are a bit more reliable and easier to test.
