Getting Started with Instagram

I think I may finally dip my toe in the water with Instagram and at the outset I'm not a big social media user and would appreciate some advice please. From my initial research it seems that IG likes images to be posted in either 1:1 or 4x5 portrait format
For scenic landscapes are people simply shooting in portrait format to post on IG, looking for an upright / square crop from a landscape format image that will suit or doing something else?
Any hints or tips regarding workflow would be greatly appreciated.
Many thanks

Quote:I put everything in a white square border, so I can use any aspect ratio I like. I use a free Android app called 'White Border' but there are many others available. You don't have to do this, of course, but if you think you might want to then best do so from the start to get a consistent look.
That sounds probably what I'm looking to do. Would you mind sharing your IG name please so I can see how it looks
TIA
