The hybrid thing is genuinely tough on console because you're locked into vanilla balance, and yeah - summoning does split your damage output. But it's not a waste if you reframe what the summons are actually doing.
They're not there to carry the fight. They're there to buy you positioning and breathing room. An atronach or dremora lord soaks aggro for like 10-15 seconds while you get behind an enemy, land a power attack, or just not get surrounded. That's the real value. If you're expecting them to solo a bandit while you afk, yeah, that sucks.
The perks that actually matter: grab the ones that boost your summon duration (the perk that extends how long they stick around), and then invest in whatever melee tree you're using - sword and board sounds like you want the block perks and maybe the shield bash ones. Summoning itself doesn't need a ton of perks to be useful; the skill levels up fast just from casting.
Real talk though - on Switch you're also hitting the performance ceiling where having two active combatants can tank your framerate in bigger fights, which makes the summons feel even more useless because they're standing around while the game chugs. That's not a build problem, that's hardware. If you want summoning to feel "good" on Switch, you might be better off going full conjurer with maybe one summon at a time, or just accepting melee as your primary and summoning as a situational tool rather than a core pillar.
What difficulty are you playing on? That changes the math a lot.
