Cringing at old posts means you changed. That’s the good kind of embarrassing.

The wince is a measurement of distance. You can only be embarrassed by an older version of yourself if the current one has different judgement, which means the feeling is evidence of growth arriving in the least flattering possible form. Someone who finds nothing awkward in their old self has either been perfect or stood still.

Leave them up or take them down, whichever you prefer. Either way, notice what specifically makes you wince and what that says about what you value now. Then assume you will feel the same about this year eventually.
