Introductory advice for an entirely new player

First and foremost, im looking for advice on beginning standard play in order to learn what cards id like to look for. So far ive noticed there is a limit of sets from the last 3 years, which has led to my next question.

What is some convenient advice on searching for synergistic value for specific strategies you want for your deck? My only current thought is finding legendary creature(s) and building off effects from there.

I am aware I should take ramp into consideration, and have a general idea of a few strategies specific colors are geared towards.

Appreciate anyone able to give good general feedback on these things!
