Hi and welcome to Blade Forums. I only own the Mcusta from the three you're considering, but I'd like to offer my thoughts.
First, you should probably edit out the links to Amazon. They're not a supporting dealer at Blade Forums and linking to non-supporting is considered a no-no. Check out BladeHQ or KnifeCenter or any of the other supporting dealers if you want to post links. I'd also caution against buying knives at Amazon. You may do fine, or you may end up with an Amazon Marketplace vendor who sells you a fake knife. If you stick with reputable knife vendors, you can purchase with a high degree of confidence.
The Megumi is a beautiful gentleman's folder. I've considered picking one up many times. I think it's biggest limitation for EDC from my standpoint is lack of a clip and size. The Megumi is a very small knife with a slender handle. I know you mentioned "minor" tasks, but such a slight knife can become tedious if those tasks involve breaking down cardboard. The lack of handle size makes it more of a dress, occasional use knife than an EDC knife. But Damn, it's a looker, isn't it? Although S30V is a serviceable blade steel, it's a bit below expectations for the Megumi's price.
I've had a couple of Mcustas and own a Tactility with the Corian scales. Mcusta makes beautiful knives with so-so fit and finish. They are mostly configured only for tip down carry, which usually doesn't work for me. If you opt for the Mcusta, bear in mind that you're paying a big junk for Japanese production costs. If the Mcusta knives were manufactured in China, they probably cost half of what they currently cost. That being said, they make beautiful knives that just seem to be overpriced and under-finished. If you can accept that, the Tactility may be your best choice. If you go to BladeHQ or Knifecenter, you'll probably find some Tactility options with wood scales and thumbstuds.
Of the three that you've suggested, I think I prefer the North Fork the best. Benchmade will take some heat for their "out-the-door" QC, but I think they're typically better than Mcusta. The North Fork strikes me as the best EDC option of the three. The blade is more suited to multiple tasks and the handle probably will offer the best ergos. Benchmade service is probably the best in the industry and their stabilize wood scales seem to hold up well. The Axis Lock is the most user friendly lock in the knife world. If we gave all kids a knife with an Axis Lock, the fidget spinner industry would be out of business!
If you're open to a fourth option, perhaps consider the Benchmade 556-1 Mini Griptilian (or 555-1 if you prefer a opening hole). I know it doesn't get you the wood scales you're looking for, but it's a huge upgrade in blade steel and the ergos are better. You can search for aftermarket options for wood scales and add them to your knife further down the line or perhaps try dyeing the gray scales. Just a thought to consider. Good luck!
