11 months is an extremely long time to be cutting. As you lose fat mass you will always also lose muscle mass, so it's definitely time to start strength training seriously again. You will need to be in a caloric surplus as you noted, but that doesn't mean you need to blow up to 30% body fat. Set your protein levels and carb levels first and then set your fat to make up the difference for your required calories. Run out your novice linear progression and then you can potential do another shorter cut.
