I thought fat finger syndrome was a real thing too when I started playing. Was pretty discouraging. Then googling "fat finger syndrome" made me realize it was a real thing.
One thing I've done is to place each finger on the chord one by one starting on the root note, plucking the string as it is placed, and doing this very slowly. Then when all fingers are down to strum the chord and say out loud the chord name. Observe your fingers, where they are in the position. Strum a couple more times. Then while keeping the chord shape slowly lift off the strings till they lose contact then drop the shape back down on the strings and strum again. Then slowly lift the shape off and slowly away, down to your knee and flex your fingers for relaxation.
Then concentrate on hitting that chord again by slowly moving the hand to position, getting the fingers into the shape, and drop them into place, say the chord name and strum. Repeat several times.
