This is one of the better deals (with coupon) for a great 68 key bluetooth mechanical keyboard layout with backlit keys. Light and portable. I have 2 of them. Unfortunately the Amazon listed one comes with blues which are great for typing feel but may be considered loud for coffee shops people in proximity.

I'm also a fan of this one since it has a slot for a tablet and volume knob but not having dedicated arrows may bother some. You can fn shift the keys in lower right to be arrows I believe (hold Fn with pinky, then ? becomes an up arrow for example). It's a perfect coffee shop keyboard if you just bring a tablet with you.

This topic can open a huge can of worms because I'm a mod in the Alberta Keyboard Community and I have everything from these cheaper Amazon/Aliexpress keyboards to keyboards that weigh 5kg and are over $1000. There is way too much variation and possibilities to reasonably discuss.
The biggest thing contributing to typing feel is the switch type and keycap type and from then on it gets deeper and deeper with plate, suspension, case, dampening materials, etc.
