I suspect the answer lies within your self, more than anything, im 35 going on 36 soon but i took the plunge, looking to get into an RHS of anything really.
I currently have a CPL, but delayed my IR for obvious reasons. So by the time the market picks up i will probably be 38 and hopefully , just hopefully, there will be positions in the freight, or small airline sector that want the more stable and im not going to say less ambitious because i think that would be incorrect, just more grateful for the opportunity to get into the RHS.
Besides if you go to CPL level only it would improve your flying skill, then you can make your decision if you want to plunge loads more money in.
I personally think if you are realistic, take your time by spreading the training, and research the arena you can fall lucky.
My first PPL instructor got his first airline job at 42 and is still with them so maybe there is a lot to be said for us older ones??
