Lets say i invest $5000 to buy sti etf using fsmone app, what is the breakdown of fees i have to pay if i want it to be keep in my cdp account compared to if i keep it in fsmone?

I just viewed some online brokerages and discovered there are so many2 type of fees, but they will show only those type of fee they charge low or $0, while dont mention other fees that maybe charge very high ? Type of fees such as :

withdrawal fee,

inactivity fee,

transfer fee,

annual custody fee,

commission fee,

trading fee,

monthly commission,
monthly activity fee,

account opening fee

Waw so many2 type of fee dont know what else need to pay besides all fees mentioned above?

​

If i want to start my very first investment by buying $5000 sti etf and keep a few (3 - 5) years dormant, which broker will be cheapest and how much the fees will be after 3rd or 5th year ?
