These are questions better answered by people who are about 5 years ahead of you , i,e. someone who got their CPL say 2-4 years ago. Unfortunately this forum is populated mainly by retired old boomers, who like me, are clueless about the difficulties and issues facing a brand new CPL holder.
My two cents says get a trade (any trade) first and learn to fly first as a hobby and then later extend it to a CPL. It’s a much longer process for sure but at least you’ll always be employable. Unless of course you aspire to driving Ubers while waiting and hoping for that first flying job.
An interesting statistic would be the number of CPLs issued versus the number actually employed as pilots say in the past five years. As clueless as I am, I don’t think it’s a pretty ratio.
