Fish for an 8 year old?

so i’m getting my jon boat put together and we have a big boat. i want to put my brother on some fish this year. last summer we tried to take him fishing and he just got angry he was satisfied for a while hooking pinfish but when he realized he wasnt gonna catch them he got frustrated. i am going to put him on some sharks but i want him to handle others to. i think im going to get him a 6ft ugly stick with a shimano sienna 2500 or 3000 with 15 or 20lb braid, for easier casting. i want to put him on sharks, ji pretty know how to fish for those just have 2 or 3 rods running a free floating mullet bluefish or whiting and one on the bottom on cut bait, and one ballooned on cut or live bait. i want to put him on some flounder possibly but not asking for those spots. i want himon some juvenile trout with constant action, catching some ladyfish for a fight. i have caught one but i really want to how to target them so hudson can catch em and i can use them for tarpon bait. i am going to try to run my boat to a barrier island so surf fish for reds and pompano for hudson. and i want him to be able to catch some lizard fish, those are a summer fish right? and how do you fish for them and where? and do you guys think a sabiki rig is to complicated for him to use without me untangling it every 2 minutes? and if he uses one can he throw it around a place i know crawling wiht pinfish and hook em? i believe he would love to catch 5 fish at a time even if their small. also do sabikis catch finger mullet or good sized muller or manhayden? i am also gonna put him on some black drum and try for reds but one thing at a time. also are spanish mackeral easy to fish for? i know where i just dont know how to fish for spanish i wanna get hudson on some myself on some for the first time and one OTF. he also has a small opsession with trolling, what can i troll for and with in the summer and where? i am not asking for honey holes of reds or trout or flounder just what you guys would consider trash fish or a not targeted species for my littl
