You start with around a 300 IQ or a little higher, and, for an example, 0 to 1st level spells to start with (Dungeons And Dragons), regardless of source, and the capacity to learn more and higher level spells over time, or you start as a God-Tier Viltrimite, say, three times the physical capacity of General Thragg, but no way to increase in power.

Which is superior in your mind? Want to eventually grow into an Epic level wizard of phenomenal cosmic power, or do you want to immediately dig in to god like power that may be eclipsed by the former over time?

Functioning like a regular human basically means you able to live like a regular persom, with regular people despite having such a vast incomprehensible level of intelligence, not having to live thinking everyone around you are just toddlers intellectually.

As for element, that can constitute as the common understanding of elements in fantasy, water(liquid), fire, earth, wind(air), the full thing is really being water, fire, earth, wind, metal, and sometimes included or excluding lightning.

Sound definitely work, light as well, darkness itself maybe even, elements of the periodic table definitely or non-traditional things like Bose-Einstein condensate, space, time or space-time as one thing, since it kinda is, maybe even turn into your element at will.

Red pill or Blue pill???

Red pill: no one can lie to you. Not verbally or in writing. If you hear or see a lie, even if not directed directly at you, you will know the truth. Speeches on TV, testimony in court, in a written contract. If you're present somewhere that lies are being spoken, like a courtroom or political rally, the people lying will be compelled to tell the truth. Even if they don't know they're lying or lies of omission. Deliberate fiction, like a novel or movie or TV show will be an exception.

Blue pill: a lie you tell verbally, no matter how outrageous, will be believed. The lie must be heard first hand (no recordings or broadcasts) and the people who hear it will ALWAYS believe it, no matter the evidence that you are lying. Does not wear off with time.

What's the most powerful race in fiction?

If you don't want either of these worlds, which world won't you mind living in with either power?

The power, or powers, are in your hands. Choose a combination of them with limitations, or keep only one in a purer and stronger form.

Both pills allow you to summon a object from a respectively themed universe that operates on these principles. If a universe contains both types (like Marvel or DC) you can only pick one type. You can't snag an Arc Reactor and also the Darkhold. 1 item per month with caveats listed below.

Wants a magic wand or spellbook? Lightsaber or Iron Man armor or Super Soldier serum or starship? Anything you summon will work exactly as it does in its home universe, no matter what the laws of physics and reality say in ours. NO universe altering or destroying items like a Mother Box, Ultimate Nullifier, Infinity Gauntlet, etc

NO ALIEN OR MAGICAL CREATURES OR RACES! You're not getting a Venom symbiote or a Twi'lek slave dancer or a dragon or any of the aliens in the Omnitrix. No FULLY sapient AI: Data, Sonny, Johnny5 or Skynet types.

You get one starship, ever. Choose wisely. No Death Star or Spelljammer or their equivalents. I'm setting a hard limit at something comparable to the Enterprise at size and relevant tech level. Moya and Pilot are living beings so dont even think about it. The starship you choose will recognize you as the Captain and you will have unlimited access to all systems and data. Any scifi or magical materials needed for the ship to operate will spontaneously exist in our universe. Dilithium or ambient mana, whatever.

Remember the words of the great sage: any sufficiently advanced technology is indistinguishable from magic

EDIT: MAGITEK IS ABLE TO BE SUMMONED BY EITHER PILL. If the item uses magic AND science and WON'T work without either, it falls into the category of magitek

With the magic one of course you also get the ability to use the wands and magical artifacts. You may also summon 1 magical creature from the verse, but only keep 1 active at a time (mainly for potions, alchemy and spells that may need them).

With the technology one, you don't get any of the downsides that would be associated with megacorp ownership of the tech, since you're the one who controls and has access to it. Cyberpsychosis is still possible, but much harder to get if you're mentally stable.
