You asked for help computing and comparing ROI. You have shown existing investments, but I didn’t see where you posted a target AA. You are asking many relevant questions.
Seems you are relying heavily on others advice, originally an advisor and now forum strangers.
This forum has a strong bias for DIY and ~3 fund portfolios. I generally believe in that. You are being giving emphatic advice in that direction. These folks don’t understand the relevance of this account to your overall portfolio or AA, or your comfort with executing the changes.
These topics are learnable and this broader forum is a good place to do that, but I feel like the direction is coming faster than the education in a one size fits all approach.
I would suggest to someone in your situation to keep asking questions, but hold off on making transactions until having accumulated some knowledge and confidence.
