National Crime Agency does a direct entry as well so worth looking at that.
I think that in order to work for the NCA you need a catalogue of spectcular failures under your belt before they even think of working with you.
For example
Steve Rodhouse is one of the highest-ranking police officers in the country and, as Director General (Operations) of the National Crime Agency, second in command of Britain's equivalent to America's FBI.
This story from the Mail is interesting
Steve Rodhouse is one of the highest-ranking police officers in the country
He has faced intense criticism over Met's investigation into 'Nick the Fantasist'
It has emerged he was in charge of the department that closed Epstein inquiry

This takes his total package at the National Crime Agency to almost £300,000

The bonus came after he was blasted for key role in Carl Beech scandal

Steve Rodhouse is not the only person of influence at the NCA with an enthusiasm for giving credence to bizarre claims of non-existent VIP paedophile rings and satanic ritual abuse.
Elly Hanson (formerly Elly Farmer - daughter of prominent Tory Brexiteer Lord Farmer aka Mr Copper) has worked as a consultant psychologist with the NCA and other police agencies and was centrally involved in the Carl Beech fiasco as reported in Private Eye magazine, described here in the Barth’s Notes blog
barthsnotes.com/2019/08/23/private-eye-looks-at-clinical-psychologist-involved-with-two-vip-sex-abuse-investigations/
and here in the Mail, with reference to the concerns raised by real expert in religious crimes Richard Hoskins

Elly Hanson / Farmer makes a habit of attending bonkers events where therapists promoting conspiracy theories about satanic ritual abuse endorse each others beliefs. Like this event for example, featuring Elly Hanson and a variety of the UK’s most notorious satan hunters including Valerie Sinason our very own Satanist Finder General.

I mention this as it seem to me that at least some of the people working at the NCA, including the Director General, are, er, not your usual run of the mill police officer. They are definitely special. To work in a sensitive position such as theirs you need to have a love of David Icke style conspiracy theories and, at least in relation to Rodhouse, a complete lack of interest in real life perpetrators like Jeffrey Epstein and his chums in high places.
OP, as you seem to lack any knowldge or understanding off police work might I suggest that you apply for a job as a Police Crime Commissioner?
They seem to have made a habit of hiring people with your special persepctive and you might find that you fit in very well :)
