Where is your current brokerage home?
Research the transaction costs to "right your ship":
--With your current brokerage,
--and lower-cost brokerages (Vanguard, Fidelity*, Charles Schwab,...).
(* Fidelity has recently announced some zero-fee index funds... if that interests you.)
Why? You may be able to transfer your account "in-kind" to a new investment home and sell your holdings cheaper there.
If you do avoid your current brokerage's selling fee, you may not be able to avoid an "account closing" fee when you leave. (It's just a cost of doing business.)
IRS netting rules. Since you believe you have a large LTCL (long term capital loss) and a small STCG (short term capital gain), if you don't have an offsetting LTCG (long term capital gain) this year, then up to $3K of your LTCL will offset ordinary income + STCG this year.

"You can net either way.
1. Net short-term gains and losses.
2. Net long-term gains and losses.
3. Net any remaining short-term gains against long-term losses, or vice versa.
If the result is positive, pay tax at short-term or long-term rates depending on the type of gain.
If the result is negative, can use $3000 to offset current-year income (if both then short-term loss used first).
Any excess loss is carried over and remains short-term or long-term."
Bottom line. You may be able to clean up everything this year for no additional tax cost. I wouldn't keep any unwanted investments as a reminder; instead, put that money to work for you.
ST/LT gain/loss and tax reporting. You should figure this out for yourself before you sell, just so you know. Why? We should know the outcome of our investing actions before we take them. Otherwise, why take the action?
But for tax reporting, if you don't figure your exact tax status before you sell, it will be done for you on the 1099B you receive for selling. Either way, your tax reporting status will be known. (However, if you know your exact tax status before you sell, then your knowledge is a double-check that the 1099B is correct. Mistakes have been made before.)
