It's a bit nuanced with lights. You don't want to overspend, however knowing some info for what to look at helps. Efficiency numbers are often exaggerated, however they give some idea of how the light is likely to perform however there's not just one metric to look for. Things like PAR (including ePAR) intensity, alongside checking the differences in the spectrum and so on.
With LEDs you wouldn't recommend blurple today, however going full spectrum gives options like using bar lights for a more consistent spread and such. An example being I wouldn't go back to an LED light without a dimmer switch, as they really come in handy for controlling the light intensity at the top of an even canopy (as too much light in a home grow, without cO2, can harm the final product).
For optimal growth, it's essential to try and maintain the right VPD, and for a lot of people it's cumbersome to do this manually depending on where you are (environment wise), and so some systems aim to automatically assist in this by monitoring the temperature and humidity and adjusting the extractor fan accordingly.
It depends on your style for sure, but it can easily get justifiably expensive depending on how you're growing. And that's not even getting into hydroponics (which may require a chiller depending on where you are).
