Implant or post & core for broken root canal-ed teeth? (Photos)

I’m a 47 years old male with no medical conditions. Last week my root canaled crown ( 4 years old) fell off breaking underneath tooth. In last week I consulted 4 orthodontist & one Periodontist. Two strongly suggested implants and two suggested post & core with crown lengthening(around 4-5 years life without affecting future implant). Does it look like a case where post & core is an option, I’m fine if it works for 4-5 years provided this will not negatively impact future implant procedure?
