ETF Overlap

Good afternoon all.

Loving Freetrade so far. I have a S&S ISA through Santander (since I was banking with them) which is half full and also my FT account which I havd been using for investment into individual companies ($MARA is doing very nicely). Recently I sold some of my positions on FT and put some of the money into ETFs for the time being.

Anyway, I’m now thinking that my ETFs might be a bit redundant. As there is a fair bit of overlap and I may be better moving some of these into different regions or emerging markets etc.

What do you think? I have:

FTSE 100 ALL WORLD. £VWRP
S&P 500 £IUSA
MSCI ACWI £SSAC
ESG GLOBAL £V3AB

FWIW I will also probably transfer my Santander ISA to Vanguard or someone in the next financial year so I get a bit more flexibility rather than their managed funds.
