I rarely sew anymore, unless it is just repairing items.
I used to sew quite a bit when the kids were young. T-shirts, shorts, dresses, curtains, aprons.....
A serger sewing machine is easy to use. Threading it is the hardest part. If you have the manual, you should be able to manage that. A serger cuts off extra seam allowance as it overcasts the seam allowance so it makes for a very nice edge.
