Personally, if you don't do futures full-time, you don't have much time to look at the market, and your personality is relatively calm, you'd better do long-term work.
But if you have time to stare at it every day and like heavy positions, you can only do short-term, but the short-term handling fee is not a small expense. I mean the kind of short-term in the day (if I do short-term, the monthly cost will account for about one tenth of the total funds).
One more thing, popularize short-term and long-term common sense. The long and short positions in general futures are different from those in stocks. Futures should be shorter, for example, futures positions for more than two weeks can be regarded as long-term One week to two or three weeks is called the center line, and less than one week is called the short line. There are also short-term days outside the day, and ultra-short-term positions that hold positions for a few minutes or even seconds.
If you haven't done it, you'd better not say which one suits you best. I suggest you try them all, just like going to the store to pick out clothes. In the attitude of being responsible for yourself, spend more time trying on a few pieces and choose the one that suits you best.
