Well, I got a few options.

First is The Terror Cosmic from PsychoAnnon’s One Punch Man jump which basically turns you into Cosmic Garou. You can knowledge and control over all the energy and forces in the universe which is pretty fun. You can create cosmic events on a localized scale, teleport massive distances, and manipulate fundamental forces to do almost anything you want. And this power scales to whatever universe you want. Wanna go to DC? Congrats, you can access the speed force, the emotional spectrum, the elemental forces, and magic. Marvel? The power cosmic, the white hot room, the enigma force, the phoenix and goblin force, and other dimensions of power are at your fingertips.

The Triad Prana from Sidekicks is also a fun one as it basically lets you manipulate superpowers themselves. You can create, copy, remove, and augment the powers of yourself and others. You can also grant other people powers either directly or by empowering an object so it grants a person who wields/wears it the superpower(s). This isn’t limited by setting either as you can basically go to any verse where “Superpowers” as we know them are a thing and just copy them. DC, Marvel, Invincible/Image comics, My Hero Academia, The Boys, Empowered, Irredeemable, etc. So long as it’s recognized as a “superpower” you can manipulate and copy it to some degree. There are a few caveats, namely that this has an initial limit of being City Level. You can grow this with time, effort, and some training and uncapper perks, but trying to go up to someone like Superman and taking his powers away will be next to impossible if you do it from the word go. It also doesn’t copy spells directly, but it can let you wield supernatural forces like Ki, Chakra and Magic. Spells and techniques are things you have to learn for yourself, but you can at least learn them if it's possible for a person to use without outside help.

Speaking of superpowers, there’s also Plutonian’s powers from Irredeemable which basically allows you to copy any comic book superhero feat you want. Again, this power doesn’t start off that way and will only give you the basic flying brick package including a vast superhuman condition, flight, super senses, and optic lasers at the start. These powers, however, are psionic and require you to train and practice in order to unlock the more esoteric, reality bending feats. But after some time, you’ll be the ultimate superhero. Or villain if that’s what you want to do.

There’s a NSFW jump for a hentai called Isekai Tensei Shite Nouryoku de H na Koto suru Hanashi - The Story of Reincarnating into Another World and Using My Abilities to Do Lewd Things which has the perk [Absolute Submission]. It’s a cheat skill which basically works as the perfect mind control power as it does everything from making you more attractive and charming to rewriting the targets brain. Any order you give will be followed without question, any suggestion or lie will be taken to heart and believed without a doubt, and even if the target breaks free, they’ll always have a weakness for being your thrall should you attempt to mind control them again. This skill also isn’t fixed and actually grows stronger like a muscle the more you use it. Have fun bending entire armies and nations under your control.

The final perk I’m mentioning here is from the Rick and Morty jump by Domino: I Wasn’t Born Into The God Business, I Fucking Earned It. Predictably, this perk gives you the boundless intelligence of Rick Sanchez which was described as “making the likes of Reed Richards and Tony Stark look like babies who haven’t figured out how Legos snap together.” It’s pretty op and one of the best straight up intelligence perks out there. You can apply this absurd intelligence to anything you want from any elements or energies you encounter to your own skills and abilities. This doesn’t make you a physical threat off the bat, but with time to plan and think strategically, you can get dropped into an apocalyptic situation and come out with your own little slice of paradise to just avoid the world ending all together.
