If you can find someone who knows 1 pocket well you could get them to play with you, ask for some weight and don't be afraid to do so

Although there are ideas and shots that are quite game specific (in 1P especially) there are still some great ideas, and most importantly it will teach you endurance for safety battles.
The # of games I have won where my opponent "lost his cool" in the safety battle, tried something of very low % and lost is staggering, when I get involved in a safety battle I usually whisper to one of my teammates "this is my favorite part" and for me it is.
Prolonged safety battles and learning to like them is something few 8 & 9ball players have in their arsenal, here is a good link with some good info and 3 nice "rules of thumb". When you have your opponent in "1 ball hell" your chances of winning the game have gone up dramatically (in 8ball).

This is good and I have something for you here it's called "flick"; there are some times when you need "absolute minimum power" so as not to peak an OB or foul, this is also good for those "touch" shots like just tapping an OB in the side from a really shallow angle. Lock your elbow in place and don't move your forearm at all just use 100% wrist action, it will take some getting used to; practice this by putting an OB 1 diamond away from the side and the CB in the center of the table and "flick" them in, it is a weird feeling at 1st but it comes in handy. Also it does get that wrist loosened up so your other shots will get a little more action when you practice this.
There is little difference between a safety type shot and any other shot, If I had a dollar for ever time I have heard someone say "I hate safes" I would be a rich man. Try to think of them in terms that you would think of them in any other shot, safeties require a little more creativity than most offensive shots (especially 8 & 9ball) because a safety that is answerable by a good safety; a "countersafety" if you will is not a good safe, so you really have to think about what their answer will be. Usually leaving a "difficult position" isn't enough against a good pool player. Good luck with this stuff and welcome to a brave new world.
I always tell my students that
99% of the time you approach a pool table with your shooting cue you have 3 choices 1. Run the table 2. Safe 3. Sink & safe (I do not mean here shoot a ball down and call safe, why so many people think that is still a mystery to me, I mean that in your plan you have the intention of ending your inning by playing a safety) Out of those 3 choices pick the best one, out of those 3 pick the one that affords you "The best chance to win the game". I have a flow chart that explains this thought process very well; if you want it just PM me your email address and I will send it to you.
