Demand for pilots does seem to be very high right now so don't rule out a jet job without trying. That said, I can tell you that it's very tiring and you're likely to lead a very miserable life in your early career (I spent over forty years sitting in various Boeings so please don't tell me what a fabulous and enriching job it is!)
What I am finding in conversation with many who have qualified and looked elsewhere is that commuter turboprops have offered an ideal mix of stable lifestyle and adequate income. None of those pilots regret not going to the LoCo's. You might try the likes of Aurigny and Loganair for starters, especially as the latter have a program aimed at returning retired crew to the skies. Whilst you won't qualify for that it does show they don't have an age issue.
