So here's what I got:

[![soul sand, soul soil, magma block, powdered snow, scaffold, slime block, water, chest, latter, bed][1]][1]

I had to fire up the old [tag:xbox-one] for a few of these, but I found the rules are the same for [tag:minecraft-java-edition] and [tag:minecraft-bedrock-edition]:

|Block(s)|Effect|
|-|-|
|Soul Sand and Soul Soil|These blocks will change behavior drastically when the player is wearing boots enchanted with any level of the *Soul Speed* enchantment. When these requirements are met, they will speed the player up, rather than slow them down (for Soul Sand).|
|Slime Block and Bed|Both of these blocks will normally make a player bounce when falling onto them, but if the player is crouched whist falling onto one of them, it will behave as a normal block and administer the same amount of fall damage as usual.|
|Scaffold|The Scaffold will allow a player to walk on top of it, but if the player  crouches they will start to descend.|
|Powder Snow|If a player is equipped with *Leather Boots*, they will not fall into the Powder Snow but rather walk on top of it.|
|Ladders and other climbable blocks|Ladders will normally move players down if they are not pressing the *Jump* key, but if a player crouches it will allow them to ascend the Ladder, but not descend.|
|Interactive blocks (Chest)|Any block that the player can interact with, such as: *Chest, Crafting Table, Furnace, etc.*, will only allow a player to use it if they are not crouched. Otherwise it will act as a normal block and allow placing of other blocks on it.|
|Water|Water has quite a few, but some of the main ones are first, the *Depth Strider* enchantment, allowing a player to move quickly underwater. And second, crouching makes a player sink faster.|
