Tempted to convert my investments from low cost ETFs (XGRO) to high interest savings ETFS (CBIL) given the current global uncertainty: thoughts?

I have a short term horizon for potentially buying land (~5 yr) and hold $100k in XGRO in my TFSA.

I know that generally, index fund ETFs are better for longer term horizons anyway, and I am feeling that it is too risky now to keep this money even in index fund ETFs given the current state of affairs in the United States.

I am considering switching to CBIL in my TFSA as a less risky alternative, but I heard “short term bond funds” may also be an option. I am very much appreciative of any advice or insight from you all.

I know we can’t predict the future but say I was feeling a bit risk averse, any unforeseen downsides in this decision other than perhaps an opportunity loss in growth between the 5% (CBIL) and potential 10%+ of XGRO if the economy does better than I expect?

Edit: I should add I have not opened a FHSA and am also wondering if I should first move my TFSA funds intended for a down payment there now, and then make this change to CBIL..
