Work, training and matches – how much extra football is actually useful at 34?

At 34, extra work can still be useful, but it should have a clear football purpose rather than being added because younger teammates are doing more. If you already train once and play once, I would ask what you are actually trying to improve. Ten or fifteen minutes of ball work, passing against a wall, receiving on different feet or some light technical repetition can be worthwhile because it is specific and easy to recover from. Adding another hard football session just to feel productive may not give you much. Your work and family week matters too. A session you can do consistently is more useful than an ambitious plan you are too tired to sustain. Keep the extra work simple, football-specific and optional around the demands you already have. If the issue is physical conditioning or recovery, that is where individual advice from an appropriately qualified professional becomes more important.
