Let me add a few more pro’s.
-Mud, snow, and slop don’t pile up on the front derailleur rendering it useless.
-Easy to change the single chainring to get just the low or high gear that you want. Mountainbike 1x chainrings come in 26T to 34T sizes.
-1×12, 1×11 drivetrains are cheaper than ever. The 1×11 Shimano Deore complete drivetrain with the 464% 11-51 cassette or the 1×12 Sram SX complete drivetrain with the 455% 11-50 cassette (both which will fit your bike) sell for around $300. If your going to spend around ~$200 to update your current drivetrain, to spend an extra $100 isn’t that much more.
-Once you go to 1x you’ll never want to go back, that’s how good it is.
