Two-bolt mountain cleats are recessed and walkable, which matters more than most road riders admit.
Verdict
If you ever get off the bike, buy mountain bike shoes. The two-bolt cleat is recessed into the tread, so you can walk normally, and the stiffness gap to a road shoe at the same price is small enough that most riders will not feel it. Road shoes are stiffer and lighter, and they are the right choice for racing and for rides where you do not intend to walk anywhere.
The cleat standard is the real difference. A three-bolt road cleat is a large plastic wedge that sits proud of the sole: excellent for spreading load over a large pedal platform, terrible for walking, and it wears out on pavement. A two-bolt mountain cleat is small metal recessed into a lugged sole, so the tread takes the ground and the cleat does not.
Stiffness is the counterargument, and at the top of the market road soles are stiffer. At mid-range prices, which is what most people buy, the gap is much narrower than the categories suggest.

You commute, ride gravel, stop at cafes, or ever have to push the bike up something. Recessed cleats mean walking across a car park does not sound like tap dancing or destroy your cleats, and two-bolt pedals shed mud far better. This is the sensible default for anyone who is not racing, and it is what most gravel and touring riders use.

You race, or your riding is entirely on road and entirely on the bike. The larger cleat spreads pressure over a bigger platform, the sole is stiffer, and the shoe is lighter, all of which are genuine advantages over hours at intensity. Just be clear that walking in them is unpleasant, cleats wear out on pavement, and slick floors are genuinely slippery.

Whichever standard you use, cleat fore and aft position and rotation matter more for comfort and knee health than the shoe does. A common starting point is the cleat under the ball of the foot with the foot rotated to its natural angle. Persistent knee pain, foot numbness or hot spots after switching shoes are fit problems worth taking to a bike fitter rather than tolerating, since they generally get worse with mileage rather than better.
Yes, and many road riders do. You need two-bolt pedals rather than three-bolt ones. The trade is a slightly smaller pedal platform and a little more weight, in exchange for being able to walk. For anything short of racing it is a perfectly good setup.
At the top of the market, meaningfully so. At mid-range prices the difference is small and most riders will not detect it over a normal ride. Stiffness matters most at high sustained power over long durations, which is why it is a racing consideration first.
SPD is Shimano's two-bolt mountain standard with a small recessed metal cleat; SPD-SL is the three-bolt road standard with a large exposed plastic cleat. They are not compatible with each other's pedals, and the shoe you buy determines which pedals you need.
For flat pedals, no, and a stiff-soled trainer works fine for short rides. Cycling shoes earn their place through sole stiffness and a fixed foot position over longer distances, which is where a flexing sole starts to cause hot spots and wasted effort.
