Nice ideas, but you do need to be aware that are many other pilots with better qualifications than the bog-standard PPL who would be willing to take on these jobs
Glider tugging means becoming a member of the club and usually they insist on at least a Silver C qualification or a BCPL. The same will go for parachute pilots, I'd think.
You really will need to think about extending your basic knowledge once the PPL is out of the way - IMC and Night Rating, tailwheel, multi-engine experience etc.
Most organisations consider people who ask your original question as a form of parasite - they want to know what you can offer them, not what you intend to get from them. This applies to any job you may interview for.
I don't mean to insult, but the days when a basic PPL could walk into an instructional job or spend a season tugging to build hours is long gone.
Airlines now recruit from pre-trained pilots and there are many out of a job
