Answer 1

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...
    })
