Training credits to use - suggestions?

Good morning,

My bank offers training credits every year for its employees to get trainings of their choosing (finance, self development, public speaking, etc.). This year I have a EUR 1,500 voucher to use, and given that I already attended a 3-week long training on financial modelling last year, I was looking into something a bit more exotic than the "advanced modelling" trainings. Also, given that 1.5k is great but not a s**t ton amount of money I would expect to be limited to online trainings or 2-3 days boot camps.

I was wondering if you attended nice trainings (online/remote/in-person Europe) that you would recommend. I am interested in the following topics, but open to any other suggestions:

- energy & infra modelling (either M&A or PF)

- Specific accounting topics (fixed assets, working capital)

- Debt modelling 

- Modelling related to listed companies

Many thanks in advance for helping me spending these 1.5k :)
