Welcome to the club

I am “only” 25 and serve during weekdays, too.
Much will depend on the style of your parish, but during weekday masses, you will most likely not asked to carry the cross or work with incense (thuriferar/navicular). But the cross is usually just carried in front of the processionw hen entering/leaving church, so tha’s quite easy if you’e got strength enough (I can’t carry our usual cross - WAY to heavy for me).
“Candle-cyrrying” might occur, but only of there are two servers or more, so you could ask your counterpart when what to do. Usually, it is just walking in and getting candles again for the reading of the evangelium.
Some parishes require due to their layout the servers also to hold the missal or any other book at certain times during mass, but that’s not always the case. A few weeks ago, I was holding the benedictionale for our priest so that he could read the blessing for a couple (they’ve been married 60!!! years).
But you’ll be asked to assist in the preparation for the eucharist (possibly fetch bread and wine if it is not standing near the altar, give bread and chalice to the priest, hand wine and water to him, assist in the washing of the hands, and after communion, pour water in the chalice so that the priest may drink it together with the left-over wine, take the cleaned vessels from the altar).
Best would be to ask your priest to take some time and teach it to you (shouldn’t take more than 15 minutes or so to go through the usual procedere of your local mass), perhaps you can write it down, or start serving on sundays with the younger ones and learn from them - weekday masses can only be easier
