Cypress e2e test with Angular Material mat-select can't set a select value

I am trying to set a mat-option value with a Cypress test in Angular 9. I have tried all of the following workarounds below and none of them works. I am using Angular Material and the mat-select component with dynamic ngFor mat-options. The selector works fine but I can't set it or get the click to work correctly on the mat-select.

Example mat-select I am using

<div fxLayout="row" fxLayoutAlign="space-between">
<mat-form-field>
<mat-label>Begin Year</mat-label>
<mat-select formControlName="beginYear" data-cy="beginYear-select">
<mat-option *ngFor="let year of beginYearOptions" [value]="year">
{{ year }}
</mat-option>
</mat-select>
</mat-form-field>


failed attempts to get the click set

cy.get('[data-cy=beginYear-select]')
.contains(yearValue.toString())
.click();


or

cy.get('mat-select')
.first()
.click({ force: true })
.get('mat-option')
.contains(yearValue.toString())
.click()


or

cy.get('mat-select[formcontrolname="beginYear"]')
.first()
.click()
.get('mat-option')
.contains(yearValue.toString())
.click();


or

cy.get('mat-select[formcontrolname="beginYear"]').then(() => {
cy.get('mat-option')
.contains(endYear.toString())
.click();
})


or

Cypress.Commands.add('selectMaterialDropDown', (formControlName, selectOption) => {
cy.get(`[formcontrolname="${formControlName}"]`).click().then(() => {
cy.get(`.cdk-overlay-container .mat-select-panel .mat-option-text`).should('contain', selectOption);
console.log('PASSED!!!')
cy.get(`.cdk-overlay-container .mat-select-panel .mat-option-text:contains("${selectOption}")`).first().click().then(() => {
// After click, mat-select should contain the text of the selected option
cy.get(`[formcontrolname="${formControlName}"]`).contains(selectOption);
});
});
});


None of these worked and basically threw an error saying mat-option can't be found. Most of the time the mat-select popup did not even appear after the click event. I have also tried adding wait calls to see if it was an async issue but the same thing happened. Any help would be greatly appreciated. I have attached some references below that I have also tried. I am confused why the popup does not appear consistently from mat-select on a click event and if it does it can't find any options.
