Hey Khaetra,
Everyone's preferences and willingness and ability to spend on a kitchen vary wildly, but getting advice and feedback can be super helpful. We just completed a non-Mustachian kitchen remodel (paid for in cash, but still quite spendypants) and I sweated every detail because I'd waited 13 years to do it and wanted to get the best bang for my buck on every single thing.
I spent hours on Houzz Gardenwebs forum reading all about kitchen layout, appliances, the virtues of various countertop surfaces and cabinet quality etc. It sounds like you're planning to do something pretty modest (and, good on you as a Mustachian!), but it's probably worthwhile if you have the funds to strategically decide what areas might be more worthwhile spending a little more on depending on what you value. You plan to stay forever, so I'd just remodel it based on your taste/preferences. For example, countertops. You mentioned possibly tiles, which many people don't like for countertops due to grout. I'd say, from reading tons of personal opinions, that more people would be happy with laminate over tiles from a utilitarian perspective. Granite tiles might be preferred for someone who places a high value on a granite look etc.
One option that is both loved and hated is IKEA wood/butcherblock countertops. They are not expensive. Some people love them and say they are easy to maintain, others say they are a pain and show every scratch and ding. Aesthetically, I think they're nice, but I've never personally had them.
My personal choices if I were in your position would be to do a laminate countertop and spend $ on lazy susan and pullout shelves or drawers for increased function as a previous poster mentioned We got drawers (mostly) on lowers and a super susan in the corner and LOVE them. Ours were part of our overall cabinet order, but you can buy those individually online and I think it would be worth the extra money.
Good luck!!
