dear brother
welcome on car care world and buhat buhat mubark for the ride, to me it was best civic model as i also had same eagle shape in past 
Aun bhai explain you well. its true synthetic waxes dont attract much dust as well longer in life compare to natural waxes so its all depend upon u i.e u like longer protection or best looks of car ? synthetic waxes give high reflections and longer life, while natural waxes give depth , deep gloss , richness in paint. since ur car is black and 7 years old so definatly its black paint in dry shape and require natural oils / waxes. i would propose u to keep the car skin on natural wax as one u have mother's just buy one detailer spray and after wax apply detailer spray wipe , detailer spray having lot of water and some wax and silicon which will help to neutarilze the surface and wont attract much dust. since u using mother wax so u can opt mothers detailer spray or u can buy armorall detailer spray price may be 550 to 600 at hyper star, its good value for money.
u can also buy armorall shampoo its coat effective as well as armorll tier spray
about microfibers chinese made good quality microfiber cloth u can get 300 to 350 or meguiars supreem shine pack of 3 roughly about rs 1500
bhai jan synthetic car sealants are for longer protection and totaly safe for any age of car skin, u can use synthetic wax or sealant without any issues , infect car sealant in base of natural wax give better protection and far better looks 
just start from shampoo wash/wax/ detailer wipe than gradually upgrade with u clay bar and glazing and sealants etc
