As a single hander, I normally back into my slip because,1) the boat fits in my slip better, 2) boarding is easier, and 3) I am at the end that reaches the piling first so I can handle lines from the helm. When the wind is high or I anticipate using a spring line, I will go bow first. Backing combined with prop walk in cross winds can yield some surprises. Here is a video that shows what happens.

With the wind and propwalk working together, it can spin the boat around out of control momentarily. My boat, if left to it's on devices in a wind will turn beam too the wind with the bow slightly more downwind than the stern. To minimize the tendency of the wind and propwalk to spin the boat around, I've found that it is better to position the boat with beam to the wind (i.e. where it wants to go on its own) before starting to back, then go to reverse, and correct the reverse course after I get the boat backing. I prefer to back down the fairway and then turn into the slip like going ahead and driving between the two pilings. I looks a little strange, but for me, it's easier than driving down the fairway bow first, then turning away, shifting to reverse and hoping that I made the turns at the right time to allow for wind or current. When backing into slip between the pilings, I tighten the wheel brake sufficiently so I can take my hands off the wheel without the rudder slamming into the stops, but not so tight that I can't override the brake. This allows me to deal with lines using both hands. However, I suggest not putting the brake on until you start to make the turn into the slip. If you get wind shifts, you can feel them better through the wheel with the brake off, and can do a better job of maintaining control.
In lots of the guides to boat handling, I hear about a pivot turn or quick turn where in one can more or less turn the boat in it's own length. Basically, it amounts to making a starboard turn with a right hand prop (port turn for left hand prop). The rudder is put over for a starboard turn and left in that position. You make part of the turn going ahead, then shift to reverse to continue the stern's movement to port and alternately do this several times until the boat is turned around. It works very well on my boat, but what is frequently skipped is that the wind and current don't care about your little game. While you are turning the boat, they are sweeping you along to somewhere else. A bit of this can be compensated for in the turning maneuver, but one needs to be careful in tight quarters using this techinque. You can easily drift down into a positon where you are trapped and can't get out without contact with other boats or pilings. I found out the hard way. And if one leaves their normal dock lines on the pilings as I do, it's a good idea to have a couple of spare lines in the cockpit (not in a locker) just in case things go wrong. If you make an unscheduled landing somewhere when things go wrong, trying to tie the boat up in a wind with only the genoa sheets is tricky.
It has been suggested by a number of people that one should practice maneuvering around a mooring bouy or float to learn how their boat handles. I went a step further and played games around a day marker when the wind was kicking up a bit (don't tie to or hit the marker however....Coast Guard doesn't like that). My boat has a good bit of propwalk initially, but once going in reverse, I can steer tight figure 8's all day. But if you try to hold a more or less static/steady position relative to the marker, you can do it going upwind, you can't do it beam to the wind, and if the wind and waves are sufficient, you can't do it backing into the wind. This last point could be important. If you are going bow first down wind and decide to abort the approach by going to reverse, you might not be able to do it. In trying to hold a steady position relative to the marker by backing upwind, there is little/no water flowing by the rudder. If you increase throttle to hold the position, you get only propwalk and no rudder control. Increase throttle more and the propwalk increases, turning the boat more into a cross wind position and you will be swept downwind. Try it when the wind is high sometimes. This means that you may not be able to back out of trouble in a narrow fairway or restricted space. If you have to back up wind in a significant wind, the boat will get sideways where you can't complete a turn to get away. And all the time, the wind is sweeping the boat down towards whatever you were trying to avoid.
