Welcome.
There's really not enough information for anyone to give you proper guidance here.
In senior living arrangements, there are senior communities where you buy your own home and the community offers amenities, such as a pool, tennis courts, fitness center, golf, etc... You live in a community, but you live independently. It's relatively the same with senior apartments.
Likewise, there are senior mobile home parks. You buy the mobile home for around $100k, and the space rent can vary from $600 to $1000 per month (Depending on location). Many are rent controlled, so the city only allows for marginal increases. If you put your remaining $700k in investments (Money Markets, Govt Bonds, High Yield Savings), you will have more than enough interest to cover any rent.
Then there are senior communities where you pay a high monthly rent, and don't actually own anything. There are community meals, laundry services, and a host of other amenities provided. The price is adjustable based on level of care.
Then there is assisted living facilities (Which you mentioned) that is more dedicated to personal care such as getting dressed, bathing, taking meds, etc..., with nurses on staff and regular visits from doctors.
Other options can be living with children in the same house, often with your own space, or living on the same property in an ADU (Additional dwelling unit). It's somewhat like a tiny home where you feel like you have your own home, but it's easy access that allows for sharing meals, and having them check on you.
There are other factors that may influence you decision (Close to family, area of the country, weather, affordability, etc...). Good luck.
