Finance Data Analyst vs PwC Deals

Hi all, I am starting my career. My goal is to become finance leader at MNC/CFO one day. I received 2 offers, what would be the best path (note: it's in Europe):

1) Amazon - Finance Data Analyst - Job: I would be more like a support to FP&A team by creating data pipelines and dashboards (using SQL/ETL, Power BI, Excel, Power Query)

2) BIG4 - PwC Deal Advisory - Job: I would work on M&A due dilligences, company valuations (DCF, multiples)

What would be better for my career goal? ▪️ From my POV, Big4 position is more interesting to me because it is more finance role, while at Amazon more data analysis/BI. However 2 things: 1) Salary: positions are in different countries, but at the end of the month, after covering all costs of living, I would be left with 1500eur if I go with Amazon, while 500eur if I go to big4 2) Growth opportunities: not sure, I really hope I will be able to transfer internally at Amazon after 1 year to real FP&A with my data analysis skills.

In case I go to big4, after max 2 years I would try to go to Amazon fp&a, but not sure about my chances then. Also then I would have experience for M&A/Corp development which could be useful maybe in my further career.

My background: ▪️ 10mos of full time Deal Advisory analyst at EY TAS (M&A, Valuations) ▪️ 6mos of fp&a internship at Amazon ▪️Holding Master in finance
