Using async/await gives a clean syntax:

const $el = await cy.find("selector")
if ($el.length > 0) {

Answer 2

it has been questioned before: Conditional statement in cypress

Thus you can basically try this:

cy.get('header').then(($a) => { 
        if ($a.text().includes('Account')) {
            cy.contains('Account')
            .click({force:true})
        } else if ($a.text().includes('Sign')) { 
            cy.contains('Sign In')
            .click({force:true})  
        } else {
            cy.get('.navUser-item--account .navUser-action').click({force:true})
        }
    })

cypress all steps are async ,, so that you should make common function in commands file or page object file,,..

    export function checkIfEleExists(ele){
    return new Promise((resolve,reject)=>{
        /// here if  ele exists or not
        cy.get('body').find( ele ).its('length').then(res=>{
            if(res > 0){
                //// do task that you want to perform
                cy.get(ele).select('100').wait(2000);
                resolve();
            }else{
                reject();
            }
        });
    })
}


// here check if select[aria-label="rows per page"] exists
cy.checkIfEleExists('select[aria-label="rows per page"]')
.then(e=>{
        //// now do what if that element is in ,,..
        })
.catch(e=>{
    ////// if not exists...
    })

I'll just add that if you decide to do if condition by checking the .length property of cy.find command, you need to respect the asynchronous nature of cypress.

Example: Following condition evaluates as false despite appDrawerOpener button exists

    if (cy.find("button[data-cy=appDrawerOpener]").length > 0)    //evaluates as false

But this one evaluates as true because $body variable is already resolved as you're in .then() part of the promise:

    cy.get("body").then($body => {
        if ($body.find("button[data-cy=appDrawerOpener]").length > 0) {   //evaluates as true
            cy.get("button[data-cy=appDrawerOpener]")
            .click();
        }
    });
