How do you cultivate taste and intuition?

Taste is built through reps. Study the greats deeply. Ask not just what looks good but why. Understand the golden ratio. Study systems that have lasted. The Catholic Church has four layers of management and has been running for over a thousand years. That is worth examining. Everything is interesting if you go deep enough. Double-entry accounting sounds like watching paint dry until you understand what problem it solved for the traders of Venice, and then it becomes fascinating.
