Generally, you can get a similar gear range with modern 1X setups as 3X setups, plus you have less weight and far fewer mechanical issues (less moving parts without a front derailleur). Most 3X setups predominantly give you more choices within a range, not more overall range. This is a result of fairly recent technology around wide-range rear cassettes.
Note: good 1X drivetrains are, counterintuitively, more expensive than 2x and 3x drivetrains. Here's a good article that explains it:
