I know what I would do—and you are _not_ going to like it:

Sounds like you need to have a meeting or a series of meetings with all of the heirs. You may as a group decide to bring in some outside help.
If the heirs are not interested in participating you have at least part of your answer.
Do not try to guess what your family members want. Get together and talk about it.
It is not my nature in a way, but I AM a rule follower. Could not think of ANY creative way for the sibling to stay in the home other than said sibling buying everyone else out, but it would be a huge burden.
You probably need to sell if that is the consensus of the beneficiaries. If they also want to keep the land in the family, I would look at leasing the farmland only. If it works out financially, the sibling living in the house rent free could take a reduced portion of the rent proceeds, which would be distributed out to the other siblings who are not living rent free on the property.
The property is NOT yours. Your duty as executor is to fulfill the wishes of the deceased as given in the will. Whether you like it, hate it, agree with it; or despise it. Do the job; or resign. It is a thankless job. No one is going to be happy, no matter what you do. So do EXACTLY what will says, and you can honestly say “I had no choice; I simply did what was instructed “
It really is that simple
Or, so what you think best; likely get sued for fraud, be ostracized by your family and be miserable. Your choice
