Career advice - Retailing Banking vs Back office (AM)

I'm looking for new perspectives into which role I should take if my end goal is a front office position in IB/HF/PE/VC/AM

Quick Summary:

Graduated with a mathematics degree in 2020, CFA level III candidate.

2 years retail banking experience (credit analyst) assessing residential loan applications, been offered a back office role in operations for a middle market alternative investment firm specialising in PE, VC & Credit.

I'm been having troubles landing any FO jobs so I'm leaning towards taking the back office role as it would provide valuable insights in the investment management space and I can hopefully leverage 'some' of the skill and knowledge going forward.

Pros of current role: Higher pay + bonus structure, work life balance.

Cons of current role: Unchallenging, skills aren't really transferrable

Pros of new role: Gain exposure to the investment space, develop holistic views of fund accounting etc and hopefully transfer those skills to FO roles.

Given my current situtation, should I consider taking the back office position or does staying in a 'front' office retail bank provide more value if my long term goal is in IB/HF/PE/VC/AM.

Thanks
